A search equivalent to a new ID so it should show up in the bread
crumbs.

This makes it possible to find words that include soft-hyphens. However,
search higlighting will not work and I have no idea how to make it work.

There is no reason why the subscription should wait for other calls
because the lock is only for one page so once the other call has
finished the work has already been done. This simplifies the lock
mechanism so there is no more loop.

Previously the rmdir could be executed when the lock directory had been
deleted by another indexer already. This could lead to a race condition
when another indexer call creates the lock again between the if and the
rmdir. This issue still exists for stale lock directories but they
normally shouldn't exist.
This also prevents the loop from becoming an endless loop when the lock
directory can't be created.
This change also fixes a syntax error in the indexer and prevents an
endless loop when the lock directory exists but can't be deleted.

This changes the HTTP stream to blocking while writing to the stream
using select() to handle timeouts. Addtionally, wwriting is done in 4k
block now (as it is done with reading).

This is supposed to fix a problem with writing to a SSL stream that is
not quite ready.

Reading from the stream continues to be non-blocking as before.

Changes:
  * XML-RPC now correctly allows leading and trailing _
  * Error messages from XML-RPC are correct
  * MEDIA_UPLOAD_FINISH has a sixth param specifying the move function
  * Not having upload rights when using media_upload throws a msg

This patch makes the plugin manager not descend into symbolically linked
directories as this behaviour is not expected from a recursive delete.

Functionality changes:
  * deleteAttachment now triggers MEDIA_DELETE_FILE (closes FS#1568)
  * deletion success msg in mediamanager is correct, even when the ns dir
    was deleted
  * media_delete changed quite a bit

I also adjusted the coding style to match our other JS classes

As discussed on the mailing list [1] this patch replaces the
COMMON_PAGE_FROMTEMPLATE with a more flexible event to better intercept page
template use.

Plugin authors need to change their plugins. Details on the event are
available at [2]
